To aZZ whom it may concern.-

Be it known that we, CHARLES J. DAVID- son and EUoLID P. WORDEN. citizens of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Condensers, of which the following is a specification, reference being had to the accompanyingdrawings, forming a part thereof.

This invention relates to jet or injection condensers. 1

The main objects of the invention are to entrain and discharge with the water the greater portion, if not all, of the air entering the condenser with the injection or cooling water and steam, thereby maintaining the desired vacuum and reducing the required capacity and size of or altogether dispensing with the dry air-pump without materially increasing the supply of injection-water, and generally to improve the construction and operation of condensers of this class.

It consists in certain novel features of construction and in the peculiar arrangement and combinations of parts, as hereinafter particularly described, and defined in the claims.

In the accompanying drawings like characters designate the same parts in the several figures.

Figure l is a vertical section of one form of condenser embodying our invention. Figs. 2' and 3 are similar views of modified forms of the condenser.

*Referring to Fig. 1, the condenser-case a, which may be of the usual inverted-pear shape or of any other suitable form, is divided into upper and lower chambers I; and 0 by a horizontally-disposed conical partition OZ. The exhaust-steam-inlet pipe 6 is attached to the top of the casing and communicates with the upper chamber I; through a downwardly-directed steam cone or nozzle f. The injection or cooling water inlet connectiong is made through one side of the case and opens into the upper chamber I; just above the partition 03. Just below said partition an air-exhaust connection it may be provided for withdrawing air, if necessary, from the upper part of the chamber 0; leads from the upper chamber 6 into the lower chamber 0 through the partition 01, by which it is supported in line with the nozzle f, projecting slightly into its upper and larger end.

A water cone or funnel z" A contracted throat j is centrally supported by a spider or radial wingslc in the lower end of the case a'below and in line with the funnel z'. To the lower end of this throat is attached a barometric or gravity tail-pipe Z, the lower end of which extends into a waterway or receptacle m below the normal liquidlevel therein. An outer tail-pipe n, surrounding the pipe Z, is attached at its upper end to the lower end of the case a in communication with the chamber 0 and projects at its lower end into the waterway or receptacle m below the liquid-level therein. These tail-pipes are made of such a length that the water will not rise between them above the throat j by reason of the vacuum produced and maintained in the condenser. To prevent a vertical or whirling movement of the water,which would diminish its velocity and force as it passes through the funnel '5 and throat j, the nozzle f is preferably provided on the outside with longitudinal guide-vanes 0 and the funnelrl and throat j on the inside with similar guidevanes 10 and q. To reduce the temperature of the air which is separated from the steam and water as they pass. through the chamber 0 and which collects in the upper partof said chamber, the partition d is preferablyprovided on its under and outer side with aircooling vanes r, and when a dry air-pump or other means is employed to exhaust from the upper part of said chamber the excess of air which cannot be entrained with the water and discharged from the condenser through the throat and inner tail-pipe a deflector sis provided to direct the air as it passes to the exhaust connection it against the partition d and its cooling-vanes r. This deflector is cast with or attached to the case a just below the airexhaust connection it and extends downwardly and inwardly toward the partition d. To prevent the splashing of water from the mouth of the throat j upwardly into the airspace around the funnel z' and partition (2, the lower end of said funnel may be surrounded by a apparatus operates as follows: The cool injection-water entering the upper chamber 6 through the connection 9 fills the annular space between the upper side of the partition d and the outer side of the funnelz'and overflows into the upper end of said funnel in a tubular or funnel form stream. The exhauststeam entering the condenser through pipe 6 is discharged downwardly with considerable force from the nozzle f into and through the funnel 2', where it comes in contact with and accelerates the flow of the surrounding stream of cooling-water, which rapidly condenses the greater part of the steam, thereby producing and maintaining a strong vacuum in the exhaust-steam pipe 6 and in the chamber 6. The tubular stream of water, with air and any uncondensed vapor that may be carried with it, is discharged from the lower end of the funnel i into the upper flaring end or mouth of the throat j, by which it is contracted and its velocity accelerated. Any air or uncondensed vapor which may escape from the water as it issues from the lower end of the funnel t' is caught in the chamber 0, from. which vapor condensedby contact with the walls of saidchamber drains into the outer tail-pipe it; but the greater part, if not all, of the air and uncondensed vapor is entrained with the accelerated stream of water into the throat j and carried down through the inner tail-pipe Z into the waterway or receptacle m at its lower end, a strong vacuum being thus produced and maintained in said chamber 0. Any air and uncondensed vapor which are not thus discharged and disposed of through the throat and tail-pipe are drawn oif through the exhaust connection it from the upper part of the chamber 0, being cooled in their passage to said connection by contact with the partition (Z and its vanes 7, which are kept cool by the injection-water in contact with the upper and inner side of said partition. In case of any interruption'in the flow of water through the throat j and inner tail-pipe Z or any increase in the volume of the injection-water which cannot be taken care of in this way. the excess will overflow the upper end of the throat 1' into the outer tail-pipe n and escape from its lower end into the waterway or receptacle m.

In certain places and under certain conditions barometric or gravity tail-pipes may be dispensed with and a pump connected with the throat and case to dispose of the water, air, and uncondensed vapor discharged from the condenser where an open waterway or receptacle is not available.

Instead of continuing both tail-pipes downward into the waterway or receptacle one of them may terminate and discharge into the other at a point above the normal liquid-level in the waterway or receptacle, as shown in Fig.

2, in which the inner tail-pipe Z opens into the outer tail-pipe 72/ above the waterway or receptacle 1%, but below the level which the water will normally assume in the outer tail-pipe on account of the vacuum in the condenser under normal working conditions, and the outer tail-pipe is reduced in size below the inner pipe. In other respects the apparatus shown in Fig. 2 is in construction and operation substantially like that shown in Fig. 1 and hereinbefore described.

Referring to Fig. 3, illustrating other modifications in the construction and arrangement of parts of the condenser, the partition or wall cZ, which forms an annular waterway extending around and above the top of funnel a, does not completely divide the case a into separate chambers, but there is free communication outside of said partition between the upper and lower parts of the space inclosed by said case. The lower end of the case is closed around the throat j, and it is provided at one side with a separate connection a) for the attachment of the overflow tailpipe n, which takes the place of the outer pipe 71. of Fig. l and is separate from the pipe Z. It is obvious that instead of running both'of the tail-pipes Z and n down into the 'waterway or receptacle we either one of them may be run into the other above said waterway or receptacle, provided the single pipe below their junction is made of sufiicient size to take care of both the main discharge and any possible overflow. The operation of this form of the condenser is essentially like that of the forms shown in Figs. 1 and 2.

Various changes other than those above pointed out in the details of construction and in the arrangement of parts of the apparatus may be made without affecting its principle and mode of operation and within the spirit and intended scope of the invention.
